Procedure
To solution of 3-hydroxyacetophenone (2.140 g, 15.72 mmol) in acetone (100 mL) was added potassium carbonate (4.344 g, 31.43 mmol), and 3-bromo-propene (2.282 g, 18.86 mmol) and the reaction was stirred at room temperature for 16 h. The solvent was removed in vacuo and water (25 mL) was added to the reaction mixture and then extracted with ethyl acetate (3×60 mL). The organic extracts were washed with brine (15 mL), dried (Na2SO4) and concentrated to give the title compound which was used as is in the next step.
